Specification of Letters Patent.

To all whom it may concern:

Be it known that I, CHARLES E. CAMERON, a citizen of the United States,residing at Collingswood, in the county of Camden and State of NewJersey, have invented certain new and useful Improvements in Detachable\Vheel-Rims, of which the following is a specification.

The principal object of the present lnvention is to improve detachablerims, by p30 8- crease the strength of the wheel an by which the rim canbe rapidly and easily applied and removed and by which the rim is heldfirmly and satisfactorily in place.

Another object of the invention is to provide for converting, atcomparatively little cost, ordinary wheel rims into detachable wheelrims. I The invention will be claimed at the end hereof, but will befirst described in connection with the embodiment of it chosen fromamong other embodiments for illustration in the accompanying drawings,in which- Figure 1, is a side view of a wheel, partly in section,embodying features of the invention. Fig. 2, is a slde view, drawn to anenlarged scale and partly in sectlon; Fig. 3, is a transverse sectionalview, and Fig. 4;, 1s a side View.

In the drawings 1 is the detachable rim and 2 is.the felly that iscarried by the spokes 3. The felly 2 consists of a wooden part or felly4 and an encircling felly band or fixed rim 5. At suitable points aroundthe wheel are provided locking devices which are all alike so that adescription of one 6 is a plate disposed in the planeof the wheel andprovided with a base 7 disposed ata right angle in respect to it andwitha notched tongue 8, narrower than the e base 7 and tongue 8 are disposedat right angles to the plane of the wheel and there is sufiicient spacebetween them to receive the spoke felly 2. The felly 4 is grooved atright-angles to the plane of the wheel where it passes between the base7 andtongue 8. The base 7 is attachedto the detachable rim 1 as by meansof rivets 9 and it extends only a part way across the folly 2,so thatthe felly band or fixed rim 5 need not be cut clear through for itsaccommodation, but is simply notched. 10, is a housing generally oblongin shape and arranged 1n the plane of Patented July 28, 19145.

the wheel. This housing rests upon a plate 11 having flanges 12'and 13which straddle the spoke .felly 2. The flange 13 is provided with ears14.- by means of which it is secured .o the side of the felly 4 as byscrews 15 and it is also provided with an opening 16 for the receptionof the tongue 8. A spring 17, arranged in the housing 10 and fastened atone end 18, carries at its other end a bolt 19. The shank 20 of the bolt19 is connected pivotall-y with a cam or eccentric finger piece '21having two cam faces 22, one at each sideof the housing and arranged tooperate on the plate 11.

To remove the detachable rim from the fixed rim the cam finger pieces 21are turned into the position shown at the top in Fig, 11, thusretracting the bolts 19 so that-the detachable rim 1 can be pulled offlaterally. The cam finger pieces 21 can then be put into the positionshown in Fig. 2 and a detachable rim can be applied by simply insertingits tongues 8 through the o enings 16 and pushing it onto the fixed rimand in this operation the springs 17- yield and permit the bolts to snapinto the grooves 1n the' tongues, thus holding the detachable rim firmlyto place.

Evidentlythe described device can be applied -to existing wheels atcomparatively little expense, since very littlealteration has to be madein them for the purpose. The alteration consists principally inlaterally notchin the fixed rim 5 for the accommoda-.

tion of the base 7 and in fitting the flanges 12' and 13 to the follyand in notching the lat ter to permit it to pass between the base 7 andthe tongue 8. I

'In ,use the parts are well protected from dirt, but they. areiso simpleand comparatively massive that a reasonable amount of dirt or dustcannot interfere with their operation. I do not desire to limit theinvention further tlian the state of the art by reason ofany terminologyor language that I may m- '1- ploy, but U WhatI claim is Means fordetaclramy connpcting fixed rims and detachable rims which comprisethecomblnation of a plate provided with a right angularlyfdisposed base.of approxiniately' half thef'width of the fixed rim and dHaptBd-foPattaohment to the detachable rim and-provided intermediate of itstop and bottomwith a groove tongue parallel with the base and spacedtherefrom for the accommodation of the felly and unnotched '10portion'of the fixed rim, 3, housing provided with a; base having'flanges adapted to strad- "dle the fellv and whereof one isprovided withan-open ing for the reception of the tongue and wlth attaching means, aspring arranged in the housing and provided vvith
